Description

Field of Invention [0001] The present invention is in the field of parts and components for vehicles. More specifically, the present invention is situated in the context of assembly systems for components of plug-in hybrid electric vehicles (PHEVs). Background of the Invention [0002] A plug-in hybrid electric vehicle (PHEV) is a category of automobile that combines a traditional internal combustion engine with an electric motor, being able to operate on both electric power and fossil fuels. These vehicles have gained significant importance due to the growing demand for more sustainable and energy-efficient transportation solutions. [0003] The Generator Power Integrated Module (GPIM) is a crucial component in PHEV vehicles, playing a central role in energy management within the hybrid system. This module integrates the functions of the generator and the power converter, being responsible for converting the electrical energy generated during the operation of the combustion engine into usable energy to charge the battery or power the electric motor. [0004] In addition, the GPIM regulates the energy flow between the battery and the electric motors, ensuring that the vehicle operates optimally. This module is fundamental to the PHEV's energy system, as it ensures that the energy generated by the combustion engine is used efficiently, as well as coordinating battery use to maximize the vehicle's electric range. [0005] The GPIM typically has a compact form designed to fit into the limited space of the engine compartment or specific areas within the vehicle's architecture, such as under the floor or near the rear axle. It appears as a metal block with various electrical connectors and attachment points, intended to connect it to other vehicle systems and ensure its stability. The precise location of the GPIM varies depending on the vehicle design, but is usually chosen to optimize space and airflow, helping to keep the module cool. [0006] Due to the critical importance of this component, it is essential that the GPIM be robust, aiming to withstand the extreme operating conditions involving temperature variations, vibrations, and exposure to external elements. The module comprises sophisticated electronic and mechanical components that require a stable environment to operate effectively. Therefore, the presence of adequate support for the GPIM is essential to ensure that it remains firmly fixed in place, preventing damage that could compromise its functionality. [0007] The GPIM module support plate is generally a two-part structure designed to be lightweight yet robust. It is attached to the vehicle chassis and the module itself, ensuring that the GPIM remains stationary during vehicle operation, regardless of driving conditions. This plate is usually constructed of lightweight yet strong materials such as aluminum alloys or high-strength composites, and is attached to the chassis or vehicle structure at points that minimize the transmission of vibrations and impacts. [0008] In addition to its primary function of securing the mount, the support plate can also play a role in heat dissipation, helping to protect the GPIM from overheating. The plate facilitates the mounting and maintenance of the module and contributes to the overall safety and performance of the vehicle by reducing the risk of mechanical failures that could compromise the operation of the hybrid system. [0009] In the current state of the art, the location of the GPIM and its support presents significant challenges for the maintenance and replacement of these components. Access to the module is frequently obstructed by other parts of the vehicle, requiring extensive disassembly of the entire section surrounding the GPIM module. This process not only prolongs vehicle downtime but also substantially increases the labor costs involved in maintenance. Furthermore, the added complexity generated by the need to remove several components increases the risk of errors during the procedure, potentially introducing new problems that could compromise the integrity of the system. Therefore, solutions that simplify access to the GPIM module are essential to reduce operating costs and increase the reliability of PHEV vehicles. [0010] To meet the needs regarding reinforcement plate support for GPIM, the prior art document CN218499430U proposes the solution discussed below. [0011] Document CN218499430U discloses a multifunctional integrated controller for vehicles that integrates several control units, such as the generator controller, traction motor controller, transmission controller, battery controller, and vehicle controller. CN218499430U reveals a high level of integration of various different components, aiming to optimize space, reduce the overall vehicle weight, and lower production costs by consolidating multiple controllers into a single module. While CN218499430U simplifies the layout of the support plate, it does not address the problem of facilitating acce
